The organizational form of shipping companies as independent entities that perform activities of transport of goods and passengers by sea occurs at the transition from the 18th to the 19th century, when it separated from the companies that had the transport and trading functions. So they created independent shipping companies, that their transport services offered to the users of transport services. Since then, the ship's company constantly developed and improved as independent carriers of goods and passengers by sea. Ship companies are very different in size, from those who have only one ship to large corporations with hundreds of ships. Modern shipping generally use loans, and their relationship with the bank and other financial houses is very important.
